Virtual City Project

Example of 3D Visualization of Lyon

Vcity Team’s research activity is anchored in the field of geometric modeling and data science, with an approach that has often led us to collaborate with various disciplines (astrophysicists, paleoanthropologists, historians, urban planners, geographers, etc.). In recent years, our project has therefore focused on modes of representation and the dynamics of the city. This theme, anchored between geometric modeling and geomatics, leads us to propose new data processing algorithms, to allow a better understanding of the territory, but also of its evolutions. The data is geometric (generally 3D) and has related semantics and topology. It often refers to the time and space in which it will evolve (rapidly with sensor data, but also over long periods of time with the evolution of city buildings, for example). The processes that we propose to consider are based on spatio-temporal, but also thematic dimensions and should allow promoting the exchange of data in an interoperable way. The standardization processes in which we are involved, for example within consortia such as the Open Geospatial Consortium (OGC), enable the creation of new standards.

The use of these data leads us to look at several scientific bottlenecks:

The scientific obstacles discussed above can only be addressed if we provide tools to access, edit, and visualize 3D data of the city. These tools are lacking in many laboratories we work with, which are from the field of Communication Science or Social Science. Virtual City project funds are provided from:

Since 2012, we strive to develop a solid software foundation supporting today several research projects, which will be detailed on this website.
